为探索柞蚕精子质量对虫体生命力的影响,以5个二化性品种柞蚕为试材,测定交配期精子质量,并在卵期、幼虫期、成虫期3个变态阶段,对柞蚕进行抗性鉴定.结果表明:柞蚕有核精子受精能力和无核精子活动能力在品种之间存在显著差异,有核精子受精能力与卵期耐高温胁迫能力呈显著正相关,与低龄幼虫对ApNPV的抗性呈显著正相关;无核精子活动能力与成虫耐高温胁迫能力呈显著正相关.说明柞蚕精子质量在一定程度上决定了卵期和幼虫期生命力,且成虫期生命力强的雄蛾产生的精子质量也相对较高.研究结果可为选育强健型柞蚕品种提供参考.
A Study on the Relationship Between the Quality of Tussah Sperm and the Vitality of Various Insect Stages
To explore the effect of tussah sperm quality on insect vitality, five bivoltine tussah varieties were used as test materials to measure the quality of sperm during mating season and identify the resistance of tussah during three stages of metamorphosis, i. e. the egg stage, larval stage, and adult stage. The results indicated that there were significant differences in the fertilization ability of the eupyrene sperm and the motility ability of the apyrene sperm between different varieties. The fertilization ability of the eupyrene sperm was significantly positively correlated with the ability to withstand high temperature stress during the egg stage, and had a significantly positive correlation with the ability of young larvae to resist ApNPV. There was a significantly positive correlation between the activity of apyrene sperm and the high-temper-ature tolerance of adults. The quality of tussah sperm to a certain extent determined the vitality of the egg and larval sta-ges, and male moths with strong vitality in the adult stage also produced sperm with relatively higher quality. The re-search results can provide reference for the breeding of strong tussah varieties.
